.a nozzle of the character described which can be adjusted to effectindependent adjustment of the discharge of cooling fluid therefrom atany one of. a plurality of difierent places along the length of thenozzle.

A further object of the invention is to provide a nozzle for applyingcooling fiuidto all points on the inner surface of a bottle or otherglass container according to a predetermined cooling pattern which canbe varied at will in zones extending longitudinally of the container.

A still further object of the invention is to providea nozzle of thecharacter described which will afford a wide range of adjustment of the,effective discharge'of coolingfiuid therefrom so' that the same nozzlecan be used to effect tempering of bottles and other glass containers ofwidely differing shapes and sizes and requiring widely differenttempering treatments' Other objects and advantages of the invention willhereinafter be pointed out or will become apparent from the followingdescription oran illustrative practical embodiment of the invention asshown in the accompanying drawing,

' which:

Fig. 8 is an elevation of a fragmentary portion of the nozzle body,showing the relation between assembled adjacent sleeve members and theirassociation with an interposed'ring sector.

A nozzle embodying the invention may comprise a tubular stem ||l havingan externally threaded end portion screwed into an interj 5 nallythreaded rotary chuckor holder l2. A jam nut 3 may be tightened on thethreaded portion H of the stem I0 against the chuck or holder l2. a l

The nozzle comprises an elongate hollow body 10 which includes a tubularinner body member I4 having internal screw threads at one end portionthereof for engagement with the externally' screw threaded adjacent endportion l5 of the stem Ill. The opposite end portion of 1 the innertubular member M may be provided with a hollow head or tip l6 which maybe of substantially conoidal or hemispherical form,v as

shown. This head may be larger externally than the tubular member l4atits juncture with the latter so as to provide a rearwardly facingshoulder ll. The head or tip l6 may be integral with the member M orseparate and con-- nected therewith in any suitable known manner.

The body ofthe nozzle also comprises an outer tubular structure whichmayinclude a plurality of rotary sleeves, respectively. indicated at l8,I9, 20 and 2|, and a plurality of combination spacing, rotation limitingand indicating members 22, each of which comprises a, major segment orsector of a complete ring.

The inner body member I4 is provided with a plurality of.long-itudinally extending narrow discharge apertures or slots 23. In theexample shown in the drawing, there are two of these slots 23. Theyare'disposed diametrically opposite each other and each extends in themember I4 from a point adjacent to the threaded connection of j thatmember with the stem In to a point adjacent to the opposite .end of themember 14.

The sleeves l8, I9, 20 and 2| may be structurally alike, althoughdifierent sleeves may be member, as presently will be described. Thede-, scription of the sleeve 2|, shown in Fig. 7, will sufiice as adescription of each of the other sleeves.

With reference to Fig. 7, it will be noted that the sleeve 2| comprisesa cylindrical member formed with one end surface thereof planiform andwith the other end surface thereot also lying in a single plane exceptfor a pair of end exten- I sions orlugs 24. These respectively arelocated at the opposite sides of an aperture or slot 25 which extendslongitudinally in the sleeve for part of the length thereof. -The lengthshown is less than half the length of the sleeve 2|. A generally similarslot or aperture 26 extends from the opposite end of the sleeve 2| inalignment arranged in reverse d positions on the inner body ing apertureor slot 21, which extends between points adjacent to the opp site endsof the sleeve.

The slot 2'! is approximately as long as the coma bined lengths of theslots 25 and- 26 and is in part diametrically opposite 'ortransverselyalined with each of the latter. These slots all may have the same width.

Each member 22, an example of which is shown to advantage in Fig. 6.comprises a major seg- Q ment or sector of a ring having inner and outerdiameters approximating those of the cylindrical sleeve 2|. The arcuatespace between the ends 28 and 29 of the member 22 is adapted'toaccommodate and to permit limited. angular bodily movement therein ,ofthe lugs 2.4 on one end of the sleeve 2| when these members are inalined conti uous relation on the inner tubular member l4, as. and for apurpose hereinafter explained. The width of the member 22 isapproximately twice that of the extent of projection of the lugs 24 fromthe adjacent end surface of the sleeve member 2 I When a member 22 isdisposed on the inner body member I4 between adjacent sleeves, asbetween the sleeves and 2|, as shown in Figs. 1, 2 and 8, the arcuategap between the ends 28 and 29 will accommodate the abutting lugs 24 ofthe adjacent relatively reversed sleevesso that the adjacent slots 25 ofthese two sleeve members form in effect a longitudinally extending slot.This arrangement also permits each of these sleeve members to beindependently rotated about its axis to a limited extent before one orthe other of its lugs 24 contacts with the adjacent end 28 or 29 of theadjacent member 22. The member 22 'is prevented from turning with thesleeve or relative to the member |4 by'the engagement of inwardlyextending lugs 30 on the member 22 with longitudinally extendingopposite grooves 01' keyways 3| on the tubular member M.

In assembling the parts of the nozzle body, as shown in Figs. 1 and 2,the sleeve 2| is placed on the member l4 with the fiat end of suchsleeve against the shoulder next to the head or tip of the nozzle bodyI. A member 22 is then placed on the inner body member |4 against thesleeve 2|, the latter being turned angularly about the axis of themember l4 so that the lugs 24 of the sleeve will be located in thearcuate gap between the ends 28 and, 29 of the member 22. The slotsinthe opposite portions of the sleeve then will be located radiallyoutward from the discharge slots or apertures 23 in the member H. Thesleeve 20 is now placed on the inner body l4 with the endwise projectinglugs 24 of such sleeve turned forwardly or toward the sleeve 2|. This isfollowed by another sleeve, specifically the sleeve l9, which is placedon the inner member l4 in a reverse position from that occupied by thesleeve 20. In'other words, the two fiat end surfaces of the sleeves I9and28 abut each other.

Another of the members 22 is now placed on the tubular member l4,followed by the sleeve l8. The relative positions of the sleeves I9 andI8 in respect to each other, and.to the intervening.

member 22, are the same as those of the sleeve 2| and 20 and theirintervening member 22.

With the arrangement just described, the longitudinal discharge slot 23in the inner member I4 relation to the alined slots 21 in these sleeves.

As best seen in Fig. 2, the arrangement of the nozzle body parts, asjust described, provides vertically overlapping discharge apertures orslots approximately like lengths along the greater part of the nozzlebody. Thewidth of the elongated streams of fluid discharge from thenozzle body at one side thereof through the slots 21 and the widthof thestreams of fluid discharge from the slots 25 and 26 at the opposite sideof the nozzle body may be adjusted from zero to the full width of theseslots by the angular adjustment of the sleeve about the axis of theangular body. This adjustment may be made independently and to differentextents in zones extending longitudinally of the nozzle bodybyindependent adjustment of the several sleeves. A set screw 32 may bethreaded through a suitable opening in each sleeve against the .innertubular member H to retain that sleeve member in its angularly adjustedposition.

The extent 'of angular adjustment of each sleeve for the purpose ofregulating the discharge of fluid from that portion of the nozzle bodyat opposite sides thereof may be predetermined nicely by the use of aVernier scale, which includes graduations 33'on the adjacentmember 22and cooperative graduations 34 on the sleeve member. the nozzle body maybe selected and adjusted accurately according to the particular servicerequirements at any time.

The head or tip I6 of the nozzle body may be I vided with dischargeorifices suitably located and of such size or sizes as conditionswarrant or 1 make desirable. In the example shown,. the stem I0 isprovided with four longitudinally extending series of spaced orifices38. The respective series of orifices 38 are. spaced angularly around Itand certainof the the periphery of the stem orifices 38 of each seriesare larger than others.

Thus, the orifices 38 which will be turned toward the thicker portionsof the neck of the bottle 31 may be larger than other orifices 38.

In using the nozzle to temper a bottle, for example, such nozzle and thebottle may be supported with relation to each other so that the nozzlewill depend within the bottle to the position desired, as to that shownin Fig. 1. It. of course will be understood that the holder or chuck l2may be'suitably formed to conduct a cooling fiuid under pressure fromany suitable source of supply (not shown) to the stem of the nozzle. Thecooling fiuid will be discharged from the nozzle through all availabledischarge orifices or outlets. Relative rotation between the nozzle andthe bottle may be effected in any suitable n known way and by the use ofany suitable known means. Diflerential cooling of different portions ofthe bottle may be effected by independent ad- Thus, the lateral fluiddischarge from ustment of the several sleeves, as required.

lhus, greater or more rapid cooling may be ef-- means (not shown) of anysuitable known construction and mode of operation for positively coolingthe exterior of the bottle or other glass container.

The length of the nozzle may be varied to meet various requirements byusing nozzle body parts of different lengths and more or less of theparts which are alike or substantially duplicates. Many other changes inor modifications of the structure of the illustrative nozzle shown inthe drawing and herein particularly described will readily occur tothose skilled in the art.'
